                         nitrogen atmospheric deposition is essential to evaluate human 
                         impacts on the air quality and nitrogen biogeochemical cycle. 
                         However, evaluation of the nitrogen deposition fux, especially in 
                         South America agricultural regions, has not been fully 
                         investigated. In this paper, we quantifed the atmospheric wet 
                         deposition fuxes of total dissolved nitrogen (TDN), dissolved 
                         organic nitrogen (DON), and dissolved inorganic nitrogen (DIN), in 
                         a region with agricultural and livestock predominance in the 
                         Southern Minas Gerais region, Brazil, from May 2018 to April 2019. 
                         Deposition fuxes of nitrogen species in the wet season 
                         (OctoberMarch) were on average 4.8-fold higher than those in the 
                         dry season, which revealed signifcant seasonal variations driven 
                         largely by the seasonality of rainfall and agricultural 
                         operations. We also found high NO3 \−/NH4 + ratios 
                         (average=8.25), with higher values in dry season (NO3 \−/ 
                         NH4 + =12.8) in comparison with wet season (NO3 \−/NH4 + 
                         =4.48), which revealed a higher relative contribution of NOx 
                         emissions from trafc sources in dry season. We also estimated the 
                         infuence of atmospheric deposition of inorganic nitrogen (N-DIN) 
                         on environmental ecosystems, being 2.01 kgNha\−1 
                         year\−1 with potential risk of acidifcation and 
                         eutrophication of 30%. Therefore, attention should be paid to the 
                         role of wet atmospheric deposition of nitrogen as a source of 
                         nitrogen environmental pollution in agricultural regions.",
